How many sprinkling zones are there for AFF systems?

The correct answer regarding the number of sprinkling zones for Automatic Fire Fighting (AFF) systems is 21. This number is established by industry standards and guidelines that dictate the design and function of AFF systems, focusing on effective coverage, response times, and overall fire suppression capabilities. Each zone is created to provide a specific area of coverage, ensuring that all parts of a facility can be adequately protected against fire hazards.

Each zone allows for better management of water flow and pressure, leading to efficient operation during an emergency. The designation of 21 zones reflects an optimal balance between resource allocation and adequate coverage, allowing for effective control of fire incidents while minimizing water damage and ensuring safety for occupants.

Understanding the correct number of zones is crucial for professionals in fire protection and safety, as it influences system design and implementation strategies.
